How to add container labels with Spring Boot `build-image`?

Question

In a regular Dockerfile I can add arbitrary metadata labels, for example:

LABEL title="My Spring Boot App"
LABEL version="1.0.0-SNAPSHOT"
LABEL authors="stewart"

These labels can be later inspected with the command

docker inspect --format='{{json .Config.Labels}}' my-spring-boot-image:latest

How can one achieve the same thing, if you are creating your Docker image using the spring-boot-maven-plugin ?

mvn spring-boot:build-image

Using the SO answer suggested in comments above, I successfully configured this:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <!--
                docker inspect <TAG> - -format='{{json .Config.Labels}}' | jq 'with_entries(select(.key | startswith("org.opencontainers.image")))'
                docker inspect <TAG> - -format='{{json .Config.Labels}}' | jq 'with_entries(select(.key | startswith("io.buildpacks") | not))'
            -->
